Shifting procedure
The automatic transmission selects indi-
vidual gears automatically, depending on:

drive positionD (
page 189) with gear
ranges (
page 193)


the selected program mode (M/C/S)
(ML 63 AMG only) (
page 195)


the position of the accelerator pedal
(page 191)


the vehicle speedWith drive positionD selected, you can use
the steering wheel gearshift control
buttons (
page 194) to influence trans-
mission shifting by:


limiting the gear range


changing gears manually
i
When the vehicle needs to be moved with
the engine switched off and the transmission set
to neutral positionN (
page 186), e.g. in an
automatic car wash, do not depress the parking
brake pedal.
!
Allow engine to warm up under low load use.
Do not place full load on the engine until the
operating temperature has been reached.
Shift into reverse gearR or park positionP only
when the vehicle is stopped.
Avoid spinning of a drive wheel for an extended
period when driving off on slippery road
surfaces. This may cause serious damage to the
drivetrain which is not covered by the
Mercedes-Benz Limited Warranty.

Transmission positions
The current transmission position appears
in the multifunction display.
1Current transmission position!
If the current transmission position does not
appear in the multifunction display due to a
malfunction, for example, make sure that the
automatic transmission is in the desired position
by carefully driving off with the transmission in
drive positionD.
ML 63 AMG:
Select program modeC (
page 195).
Do not limit the gear range.
Effect
ì
Park position
Shift into park positionP only
when vehicle is stopped. The
park position is not intended to
serve as a brake when the vehi-
cle is parked. Rather, the driver
should always set the parking
brake in addition to shifting into
park positionP to secure the
vehicle.
If the vehicle’s electrical system
is malfunctioning, the automatic
transmission could remain
locked in park positionP.
Have the vehicle checked as
soon as possible by an autho-
rized Mercedes-Benz Light
Truck Center.
!
SmartKey:
If you turn off the engine using the SmartKey and
remove the SmartKey from the starter switch,
the transmission will shift to park positionP
automatically. Keep in mind that turning off the
engine with the SmartKey alone will not auto-
matically shift the transmission to park
positionP. Only when the SmartKey is removed
from the starter switch, will the transmission
automatically shift to park positionP.
KEYLESS-GO*:
If you turn off the engine using the KEYLESS-GO
start/stop button and open the driver’s door, the
transmission will shift to park positionP auto-
matically. Keep in mind that turning off the en-
gine using the KEYLESS-GO start/stop button
alone will not automatically shift the transmis-
sion to park positionP. Only when the driver’s
door is opened, will the transmission automati-
cally shift to park positionP.
Even though this is possible, make it a practice
to always shift into park positionP before turning
off the engine and removing the SmartKey from
the starter switch, or when using KEYLESS-GO*,
before turning off the engine with the start/stop
button and opening the driver’s door.

190 Controls in detailAutomatic transmission!
If you want the gear position to remain in
neutral positionN (for example when the vehicle
is pulled through a car wash)


do not remove the SmartKey from the starter
switch
or, when using KEYLESS-GO*


do not turn off the engine using the
KEYLESS-GO start/stop button* and open
the driver’s door
Otherwise, the transmission will shift to park
positionP and lock the wheels, preventing the
vehicle from being pulled through a car wash.
Effect
í
Reverse gear
Shift into reverse gearR only
when the vehicle is stopped.
Effect
ë
Neutral
No power is transmitted from the
engine to the drive axle. When
the brakes are released, the
vehicle can be moved freely
(pushed or towed).To avoid damage to the trans-
mission, avoid shifting into
neutral positionN while driving,
except:
If the ESP
® is deactivated or
malfunctioning:
Shift into neutral positionN only
when the vehicle is in danger of
skidding, e.g. on icy roads.
ê
Drive
The transmission shifts
automatically. All forward gears
are available.
!
Coasting the vehicle, or driving for any other
reason in neutral positionN can result in trans-
mission damage that is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
G
Getting out of your vehicle without shifting
into park positionP is dangerous. Also, park
positionP alone is not intended to or capa-
ble of preventing your vehicle from moving,
possibly hitting people or objects.
Always set the parking brake in addition to
shifting to positionP (
page 65).
When parked on an incline, turn the front
wheels towards the road curb.
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.

Driving tips
Accelerator position
Your driving style influences the
transmission’s shifting behavior:
Less throttle Earlier upshifting
More throttle Later upshifting
Kickdown
Use kickdown when you want maximum
acceleration.
Press the accelerator past the point of
resistance.
Depending on the engine speed the
transmission shifts into a lower gear.

Ease on the accelerator when you have
reached the desired speed.
The transmission shifts up again.Stopping
When you stop briefly, e.g. at traffic lights:

Leave the transmission in gear.

Hold the vehicle with the brake.
When you stop for a longer period of time
with the engine idling and/or on a hill:

Set the parking brake.

Shift into park positionP.
Maneuvering
When you maneuver in tight areas,
e.g. when pulling into a parking space:

Control the vehicle speed by gradually
releasing the brakes.

Accelerate gently.

Never abruptly step on the accelerator.
Warning!
G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Children could shift the
automatic transmission out of park
positionP, which could result in an accident
and/or serious personal injury.

192 Controls in detailAutomatic transmissionRocking the vehicle
Rocking the vehicle by shifting between
drive positionD and reverse gearR can
help free a vehicle stuck in mud or snow.
The engine control system of this vehicle
electronically limits shifting between drive
positionD and reverse gearR to very low
speeds, i.e. approx. 5 mph (9 km/h). To
shift between drive positionD and reverse
gearR, move the gear selector lever past
the resistance point up or down.
Working on the vehicleHill start assist system
On uphill grades with a gradient angle of
more than 5°, the hill start assist system
maintains the pressure in the brake sys-
tem for approximately 1 second after you
have released the brake pedal. Therefore,
you can start off smoothly without the
vehicle moving immediately after releasing
the brake pedal.The hill start assist system is inactive


when starting off on a level road or
downhill grades


with the transmission in neutral
positionN


with the parking brake set


if the ESP
® has switched off due to a
malfunction
Towing a trailer
If you tow a trailer, note the following
points:


Manually shift to a lower gear range
(page 193) if the transmission hunts
between gears on inclines.
A lower gear range and reduction of
speed reduces the chance to overload
or overheat the engine.
For more information on trailer towing, see
the “Operation” section (
page 342).
Warning!
G
When working on the vehicle, set the
parking brake and shift to park positionP.
Otherwise the vehicle could roll away.
Warning!
G
The hill start assist system is not designed
to function as a parking brake and does not
prevent the vehicle from moving when
parked on an incline.
Always set the parking brake in addition to
shifting to park positionP.

ML 63 AMG:
For information on using the steering wheel gear-
shift control in program mode M, see “Shift pro-
gram (ML 63 AMG only)” (
page 195).
!
Allow engine to warm up under low load use.
Do not place full load on the engine until the
operating temperature has been reached.
Shift into reverse gearR or park positionP only
when the vehicle is stopped.
Avoid spinning of a drive wheel for an extended
period when driving off on slippery road
surfaces. This may cause serious damage to the
drivetrain which is not covered by the
Mercedes-Benz Limited Warranty.
i
You cannot shift with the steering wheel
gearshift control buttons when the transmission
is in positionP,N orR.
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced
vehicle control. Your vehicle’s ABS will not
prevent this type of loss of control.i
To avoid overrevving the engine when down-
shifting, the transmission will not shift to a lower
gear if the engine’s max. speed would be ex-
ceeded.
